Cancer drug observed at work

Using a Raman microscope, researchers have studied at which targets the cancer drug Neratinib binds in cells and how its chemical structure changes. Compared with other techniques, this method offers a considerable advantage, as it is not necessary to apply a label to the drug that would indicate its distribution indirectly; rather, the drug itself can be monitored.
